Inventor: KURODA SOICHI
IPC: E01C5/00
Filed: 1995-11-29
Abstract: PROBLEM TO BE SOLVED: To enhance the convenience in handling, and eliminate the sense of incompatibility when a road laying member is used for the side channel of a sidewalk or the like by sticking tiles onto a water permeable board, and by arranging empty joints of the joint parts between tiles, so that water can be permeated through the joint parts and the permeable board. SOLUTION: A side channel cover 1 is made up of a water permiable board 3 to be fitted to a frame body 2, and tiles 5 that have been stuck onto the permiable board 3 with joint intervals 4. The permiable board 3 is made up in such a way that slits 6 are formed to the parts corresponding to the joint intervals 4 of the tile 5, and that water can be permiable through both the joint intervals 4 of the tiles 5 and the slits 6 of the permiable board 3. The side channel cover 1 is constructed by placing the frame body 2 on the work executing part, and then by placing on the frame body 2 a permeable board 3 on which tiles 5 have been stuck with a specified joint intervals 4.

Title: Control system of inverter for solar power generation
Inventor: SHIRAISHI TOMOO
IPC: G05F1/67
Filed: 1986-12-29
Abstract: PURPOSE:To operate an inverter circuit in the vicinity of an optimum operating point of a solar battery, by reducing only a portion by which an optimum operating point voltage is boosted in summer, without executing a temperature compensation of 100% of the battery. CONSTITUTION:A temperature compensation effect setting device 5 regulates a temperature output signal from a temperature detector 4 to 30-90% being a suitable ratio which is below said signal, by which a reference voltage value is compensated. It will suffice that a compensating portion of a temperature characteristic is small, therefore, a temperature detector 4' is attached adjacently to an inverter side. As a result, a circuit required for the temperature detector 4 placed adjacently to a solar battery 1 can be shortened remarkably. As for the detector 4', a silicon diode is desirable. A temperature characteristic of a silicon solar battery has a characteristic of -2mV/ deg.C, and a forward current of the silicon diode also has a temperature characteristic of -2mV/ deg.C. Accordingly, when the diode is used for the temperature detector in the forward direction, the compensation can be executed simply.

Title: Semiconductor optical element and its manufacture
Inventor: OKU SATORU
IPC: H01S5/00
Filed: 1997-11-13
Abstract: PROBLEM TO BE SOLVED: To strictly stipulate the positional relation between the end faces of a laser resonator and a periodic structure of refractive index in the resonator. SOLUTION: After an active layer 2, a clad layer 3, and an SiO2 film 11 have been successively formed on a semiconductor substrate 1, a line space pattern 12 in which liens having widths (a) are arranged at regular intervals (b) are formed on the SiO2 film 11, and window regions 13 are formed on both sides of the SiO2 film 11. Then an etching mask 14 and etching mask window regions 15 are formed by transferring the pattern 12 to the SiO2 film 11. Thereafter, grooves 4 are formed by performing reactive beam etching on the substrate. Since the reigns of the grooves 4 are narrower than the window regions 15, a micro-loading effect is exhibited and the etching rate of the substrate 1 becomes slower than that of the window regions 15. Therefore, worked sidewalls 5 which become the end faces of a laser resonator are formed at the same time as the forming of the grooves 4.

Title: Degenerative operating method for electronic equipment of its fan fault
Inventor: KUBOTA AKIRA
IPC: G06F1/20
Filed: 1990-11-20
Abstract: PURPOSE:To reduce the number of times of system down resulted from fan defects by comparing the counted number of defective fans with an allowable number of defective fans and shifting the operation of electronic equipment to degenerative operation. CONSTITUTION:A comparison table on which the allowable number of defective fans out of plural fans 4 is set against each circuit board number inserted into the slot 3 of electronic equipment is stored in a memory 7. When the electronic equipment is made to rise, a CPU 1 counts the number of circuit boards inserted into the slot 3 and stores the number N1 of allowable defective fans corresponding to the counted number of circuit boards in the memory 7 after selecting the number N1 from the comparison table. A counter circuit 5 counts the number of defective fans whenever a fan alarm is detected and informs the CPU 1 of its output M1 and the CPU 1 shifts the operation of the electronic equipment to degenerative operation when M1>N1. Therefore, the system can be operated without system down until the prescribed number of fans comes to defective.
